#LOW BATTERY INDICATOR CIRCUIT DIAGRAM HOW TO#

In this article, we will learn how to design a simple 12V battery charge level indicator using Op-Amp.Īlthough the Battery level is an ambiguous term because we can't really measure the charge left in the battery unless we employ complex calculations and measurements using a Battery Management System. We have already discussed more about batteries and how they work in our previous articles. which have higher energy storage capacity and high operating temperature range. With the advent of technology, we are seeing new batteries invented like Li-air Batteries, Solid State Lithium batteries, etc.

There are many different types of batteries like Lead-Acid, Ni-Cd, Lithium-Ion, etc.

Batteries, the world as we know it would not exist. It is safe to say without the invention of these electrochemical storage devices a.k.a. In the modern world, we use batteries in almost every electronic gadget from your handheld mobile phone, digital thermometer, smartwatch to Electric Vehicles, aeroplanes, satellites, and even Robotic Rovers used on Mars whose battery lasted around 700 sols (Martian days).
